Abstract: The effect of irrigation schedules on biophysical, biochemical and yield of tomato genotypes were evaluated in the field experiment at KRC College of Horticulture, Arabhavi, Karnataka. The experiment was laid out in a factorial randomized block design with thirteen genotypes and two replications. Water stress was imposed two weeks after the transplanting to all the genotypes in two stress conditions viz. the IW/CPE ratio of 0.40, 1.20 and farmers practice as control. Furrow irrigation was given when the pan evaporation reading reached 41.66 mm (1.20 IW/CPE ratio) and 125 mm (0.40 IW/CPE ratio) using V notch. The genotypes which perform better under 0.4 IW/CPE ratio, PUSA 120 had which maximum total chlorophyll content with better yield of 1.48 kg/ plant, EC 638519 had maximum proline which recorded yield of 1.47 kg/plant and genotype EC 608362 maximum photosynthetic rate and it recorded maximum of yield per plant of 1.65 kg/ plant. With all these growth, biochemical, biophysical and with yield record we can categories PUS 120, EC 638519 and EC 608362 as drought tolerant genotypes.
